Tinosan SDC: Preservative and deodorant
Tinosan is suitable for surfactant mixes, gels, and emulsions that have a pH below 7, and it will not cloud your products. It is not compatible with cationic ingredients so please don't use it in your conditioners or lotions using BTMS as the emulsifier, or any products that include cationic polymers, like polyquat 7 or honeyquat. Don't expose products with Tinosan to light, so make sure you package them in opaque containers, and keep them in a cool dark place. Although Tinosan doesn't have a shelf life as such, it is recommended to use products including this preservative within a year. Store the Tinosan in a cool, dark place in your workshop.
I cannot stress this whole opaque containers, storing in a cool dark place part. This product will degrade with light and won't act as an effective preservative if you are putting it into clear bottles or jars. I know I have the deodorant products you'll see over the next few days in clear containers - that's all I had in the house at the time, and I wanted to test the feeling and consistency of the products that day. Make sure all your containers are opaque!
It is suitable for clear products and you can combine it with other preservatives if you want. Tinosan is water soluble, so it's not appropriate for anhydrous products. When using this preservative, remember to include it at 0.1% to 0.3% in the cool down phase (under 50˚C) of your product. When we're making deodorants, we use Tinosan around 0.3% in the cool down phase as an anti-bacterial ingredient. It's considered a deodorant active as well as a preservative.
